David Phelps left the game with right elbow inflammation.

I thought it was just because he was pitching like crap, and if that were the reason it would have been justified, but turns out David Phelps' early exit tonight was due to him feeling pain in his right elbow.

He wasn't very good tonight, but he had been pitching well of late and had settled in nicely as one of Joe's more reliable rotation options. The Yankee rotation has been ravaged by injuries this year and they can ill afford to lose anybody else. More on this story as it comes out.
